The acute therapeutic effect of enalapril,an angiotensin converting enzyme inhibitor (ACEI),in reducing blood pressure and urinary albumin excretion rate(UAER) were assessed in 32 NID- DM and 13 essential hypertensive patients.After treatment for three days,24-h blood pressure and UAER in NIDDM patients were reduced significantly.UAER of essential hypertensive patients were reduced while in hypertensive patients UAER were reduced,but blood pressure except night SBP remained unchanged. This study suggests enalapril may have a specific protect effect on kidney which is independent of the de- crease in systemic blood pressure.

Background The visual system of animal have to optimally adjust in various environmental conditions in order to obtain stable and effective visual funetion.However,the color vision system of animals which encounter uncertainty of spectral signals should be plastic.Whether the densities of various cones and expression of opsins change with long-time spectral deprivation is unclear.Objective This study was to investigate the changes of cone density as well as the expression of corresponding opsin and mRNA following the long-term illumination of monochromatic light.Methods Thirty 3-day-old guinea pigs were randomized into 3 groups and exposed tO the 530 nm green light,400 nm purple light and white light for consecutive 8 weeks respectively.The flat-mounted retinal sample was prepared and divided into dorsal zone,ventral zone and mixed zone anatomically according to the distribution of difierent light-sensitive cone.The changes in density of cone cells sensitivited to different colored light were detected by single-1abel or double-label immunocytochemistry.The levels of opsin and its mRNA were determined using Western-blot and real-time PCR respectively.Results The density of green-sensitivity cones was significantly different in the dorsal zone of retina among green light group,purple light group and white light group (F=234.28,P<0.01).Compared with white light group,the density of green-sensitive cones in dorsal retina of green light group was obviously higher but that of purple light group wag evidently lower(q=389.68,P<0.01；q=67.11,P<0.01).No significant difference was found in the density of purple-sensitive cones in the ventral zone of retina among green light group,purple light group and white light group(F=3.14,P>0.05).The density of coexpression of the mixed cone cells was increased in green light group(q=157.55,P<0.01)but decreased in purple light roup (q=254.85,P<0.01)in comparison with white light group.The expression levels of green-opsin and green-opsin mRNA in green light group was significantly elevated(q=184.45,P<0.01；q=4.71,P<0.05),but those of purple light group were evidently declined(q=5.87,P<0.05；q=346.66,P<0.01)in comparison with white light group.There was no statistically significant differences were found in the expression of purple-opsin and its mRNA among all the groups(F=1.24,P>0.05；F=3.27,P>0.05).Conclusion After the exposure of long-time monochromatic light illumination,monochromatic cones density and its opsin in guinea pig occur the corresponding alteration to gain good spatial vision as a compensatory reaction.These outcomes imply that there is some plasticity during the development of color vision.The increase of green-sensitive cones might be from the differentiation of coexpression cones in transition region.

Doctor WANG Zhi-zhong in the Southern Song Dynasty proposed the acupoint view of "location of disease", which explained the connotation of acupoints from the angle of clinic. Its meaning included two levels, one level meant pathological change on the body surface, that was the location of acupuncture diagnosis-treatment, and the other one indicated that the body surface which was the reflecting point of pathological change on the distal area or inside the body was the location of acupuncture diagnosis-treatment. The specific connotations of clinical acupoints were: location of pathogenic factors or reflection of pathogenic factors, regularity between acupoints un- der disease and specific organ, morphological differences and positioning variability after acupoints under disease, and acupoints examination, diagnosis and treatment.

Objective To isolate and identify the adult neural stem cells from the parenchyma of spinal cord in adult mouse.Methods The parenchymal spinal cord from adult mouse was dissected and dissociated by mechanical trituration.The tissue suspension was cultured in serum-free DMEM/F12 medium supplemented with EGF and B27.The cell colonies generated from a single cell were screened by limited dilution and incubated with BrdU.The cell colonies were transferred into medium with serum to induce differentiation.The cells were identified with antibodies to Nestin,BrdU,MAP2 and GFAP by immunofluorescence staining.Results The cells were cultured for seven days to generate proliferative neurospheres.The majority of cells in these neurospheres expressed Nestin and were differentiated into MAP2-positive cells and GFAP-positive cells in medium containing with fetal bovine serum.Conclusion A significant number of neural stem cells are present in the parenchymal adult mouse spinal cord and can proliferate and also give rise to neurons and glia in vitro.

As a member of orphan G protein-coupled receptors (oGPCRs), hGPCRc was cloned from human colon tissue and analyzed by bioinformatic softwares. It was showed that the corresponding amino acids of hGPCRc formed seven-transmembrane domains as the key characteristic of GPCRs. Then, the recombinant GFP-hGPCRc was constructed by fussing hGPCRc into pEGFP-N1 carrying green fluorescent protein (GFP) gene, and CHO-K1 cells were subsequently transfected with the GFP-hGPCRc or pEGFP-N1. The green fluorescence protein expression in the two different transfected cells was observed under the laser scanning confocal microscopy (LSCM). It was showed that green fluorescence protein was distributed in the whole bodies of the cells transfected with pEGFP-N1, but mainly distributed on the plasma membrane and cytoplasm membrane transfected with GFP-hGPCRc. Thus, the localization on the membrane of hGPCRc was accorded with the predication by bioinformatic analysis. The expression analysis of hGPCRc by RT-PCR indicated that hGPCRc was abundantly expressed in heart, kidney, cerebel and colon etc., but absent in liver, cerebra, small intestine and muscle etc. The expressing profile of hGPCRc could provide some useful clues to understanding its effects on embryonic development and physiological functions.

Objective To compare the odds ratio of waist circumference (WC) and/or body mass index (BMI) on cardiovascular risk factors. Methods Data on a cross-sectional study involving 41 087 adults (19 567 male, 21 520 female) from the 2002 China National Nutrition and Health Survey were examined. According to the obesity definition of the Chinese Working Group on Obesity for Children (WGOC) (BMI, 24 and 28 kg/m2; WC, male 85 cm, female 80 cm), the study population were divided into 9 groups. The prevalence and odds ratio (OR) of cardiovascular disease (CVD) risk factors were compared among these 9 groups. Variation and standard β were indexes being used to compare the likelihood of BMI and/or WC on CVD risk factors. Results Within each of the BMI categories, with few exceptions, indices levels on CVD risk factors were significantly increased (decreased for HDL-C levels) with the increase of WC, and vice versa. After adjusting the effects of age, sex, income, education, sedentary activity and dietary factors, the ORs of hypertension in adults with higher WC within each of the BMI categories were higher than adults with lower WC, and the ORs of hypertension in adults with higher BMI within each of the WC categories were higher than adults with lower BMI. Similar trends were found for high fast plasma glucose (FPG) and dyslipidemia. The variation in CVD risk factors explained only by WC and BMI were quite similar,but slightly larger when combined WC with BMI. Standard β was higher on BMI when predicting systolic BP and was higher on WC when predicting TG, TC and HDL-C. Conclusion BMI and WC were independently associated with the risk factors on CVD.To combine the BMI and WC, the results could accurately evaluate the risk of CVD, thus to provide substantive evidence that the WGOC cutoff points for the WC might help in identifying those population under increased risk.

OBJECTIVESTo investigate the effects of Cyclosporin A (CsA) on spermatogenesis and expression of FasL and Fas in the contralateral testis after the unilateral testis was injured.

METHODS60 mice were randomly divided equally into groups A (control), B (the unilateral testis was injured by glacial acetic acid), C (excision of ipsilateral testis at 6 hours after the unilateral testis was injured by glacial acetic acid) and D (CsA within 6 hours after the unilateral testis was injured by glacial acetic acid). Sperm density and sperm motility were evaluated after 4 weeks. Expression of FasL and Fas was performed by immunohistochemistry (SP method). The positive cells with SP staining in seminiferous tubules were calculated.

RESULTSSperm density and sperm motility in group D were significantly increased compared with group B(P < 0.05). Expression of FasL and Fas in group D decreased significantly compared with group B (24.3 +/- 7.0 vs 37.8 +/- 5.8 and 17.8 +/- 4.3 vs 32.4 +/- 3.6, P < 0.05).

CONCLUSIONSCsA decreased expression of Fas and FasL and maintained spermatogenesis in the contralateral testis after the unilateral testis was injured by glacial acetic acid.

PURPOSE: The systemic inflammation biomarker, Neutrophil-to-Lymphocyte Ratio (NLR), has been reported as one of the adverse prognostic factors for hepatocellular carcinoma (HCC) patient. The purpose of this study was to evaluate whether NLR could predict the risk of recurrence and death for the HCC patient, according to Milan criteria after hepatectomy. MATERIALS AND METHODS: Retrospective analysis was performed on a database of HCC patients who underwent hepatectomy between March 2001 and December 2011. The cutoff value of NLR was decided by receiver operating characteristic (ROC) curve analysis. Univariate and multivariate regression analyses were performed to identify predictive factors of recurrence and death. RESULTS: A total of 213 patients were included in the present study. The median follow-up period was 48 months. One hundred and seven patients were experienced tumor recurrence; forty of them recurred within 12 months (early recurrence). NLR ≥1.505, albumin ≤3.75 g/dL, microvascular invasion and high grade of cirrhosis were found to be independent factors for adverse recurrence-free survival in multivariate regression analysis. And NLR ≥1.945 was also found as a prognosis factor for early recurrence by univariate regression analysis. CONCLUSION: Elevated preoperative NLR can be easily obtained and reliable biomarker for assessing the tumor recurrence and early recurrence of Milan criteria HCC after the initial hepatectomy.
